[urq] aan cam sensor

[Wylie Bean]

The (in)famous tuna can sensor. There's some good info in the quattroworld  
urS-cars FAQ and i believe Dave Forgie's made a few posts related to it on  
the s-car-list here

Subject: [urq] aan cam sensor

I've been examining my AAN donor a little closer today . 

Strange , there's a distributor like something on the back of the cilinder  
head . 
It's not the plug an AAN should have . 
The best way I can describe it is like the bottom half of a distributor ,  
with the cap removed and some 
kind of lid on it instead  . A 3 wire connector arrives on it . 

This is most likely the  cam position sensor ,  but I've never heard of this  
kind of setup . 
The cam senor should be located on the rear of the timing belt pulley . 
Looking at the wiring loom , it does seem original . No cut or folded wiring  
, no solder or other joints . 
Harness is intact and not tampered with 
And it has all the other AAN parts like the coil packs and the ignition  
amplifiers , the bracket with all the connectors etc . 
all located in the locations I'de expect them to be , and all looking very  
original . 

So my best guess is that this is a very early aan , wich has a slightly  
different 
cam position sensor . No record of it in etka , not mentioned in the shop  
manual .
